Configuration and Setup
Start-Up Sequence
When power is turned on, the actuator will automatically calibrate to determine the closing point of the valve.
Calibration can take up to 10 minutes depending on the valve’s position at start-up. During the calibration actuator,
the display will show “CAL”. Hereafter it will proceed to the normal operation mode (according to control signal).
If no control signal is detected, flush is started if enabled in the programming menu (enabled by default), opening the
valve to 5/6 of fully open. Actuator display will show “FLUSH” until control signal is detected.
At first start-up please enter programming menu to set actuator settings.
